Big enough? Sampling in qualitative inquiry
Overall Guetterman (2015) found that the mean sample size was 87 participants. However the range of participants was from 1-700. Regarding differences by methodology, he found case studies had a mean sample size of 188; ethnographies 128; grounded theory, 59; narrative inquiry, 18; and phenomenology, 21. (Guetterman, 2015: 10-13). So there ...

Case Study Sample Size. Typically, a case study has a sample of one (i.e., the bounded case, but note that sam - pling can also occur within the case), unless the research project is a multiple-case study. In a multiple-case study, having three to four distinct cases for comparison is probably the most cases that one can realistically handle.

Sample adequacy in qualitative inquiry pertains to the appropriateness of the sample composition and size.It is an important consideration in evaluations of the quality and trustworthiness of much qualitative research [] and is implicated - particularly for research that is situated within a post-positivist tradition and retains a degree of commitment to realist ontological premises - in ...

The logic of small samples in interview-based qualitative research
Since such a research project scrutinizes the dynamic qualities of a situation (rather than elucidating the proportionate relationships among its constituents), the issue of sample size - as well as representativeness - has little bearing on the project's basic logic.
What Is Sample Size?
Different types of studies might require different sample sizes. For example, a study aiming to understand a rare disease might need a larger sample size to ensure it captures enough cases for analysis. Whether you choose to conduct an observational study, cohort study, case-control study, or experimental study will affect the sample size you need.
